<ul><li>Building on this progress, I’ve extended my existing Node.js API boilerplate with a new tool LLM Codegen.</li><li>A standalone feature enables the boilerplate to automatically generate module code for any purpose based on text descriptions.</li><li>The generated module comes complete with E2E tests, database migrations, seed data, and necessary business logic.</li><li>This boilerplate follows specific structures and patterns that I believe are of high quality.</li><li>The generated code after the first stage is clean and adheres to vertical slicing architecture principles.</li><li>The second use case involves generating DB migration with the appropriate schema and updating the seed script with the necessary data.</li><li>The final use case is generating E2E tests, which help confirm that the generated code works correctly.</li><li>LLM clients are OpenAI and Claude.</li><li>The core remaining work is performed by micro-agents: Developer, Troubleshooter, and TestsFixer.</li><li>During the development and testing, it was used with various module descriptions, ranging from simple to highly detailed.</li></ul>
